The first purpose of this paper is to resolve the mixed unit by analytical geometry and function and to clarify the difference between them, and the second one is to clarify the learning content of function and analytical geometry, and the third one is to explore how to instruct analytical geometry in junior high school.
As a result, it can be considered that common representation of analytical geometry and function is the graph in the side of each shape, but it is found that the meaning of shape, which is derived from the side of each concept, is different.
